Gregarina tropica n. sp (Apicomplexa: Eugregarinorida: Gregarinicae: Gregarinidae) parasitizing the brown-winged earwig, Vostox brunneipennis (Dermaptera: Labiidae), in the Texas Big Thicket

Gregarina tropica n.sp. (Apicomplexa: Eugregarinorida) is described from the brown-winged earwig, Vostox brunneipennis (Dermaptera: Labiidae) collected from the Turkey Creek Unit, Big Thicket National Preserve, Tyler County, Texas. U.S.A. We review the morphometric data and nomenclatural status of the 8 previously described species of Gregarina infecting earwigs and recognize 7 valid species: Gregarina ovata, Gregarina nalae, Gregarina megaspora, Gregarina ambigua, Gregarina fallax, Gregarina chelidurellae, and Gregarina labidurae. Although apparently valid taxa, the latter 3 species are very poorly described and thus considered species inquirendae pending new collections and redescription, Gregarina forficulae is recognized as a junior synonymy of G. ovata.
